(a) True

(b) False

I have been asked this question in unit test.

My question is taken from Round Off Effects in Digital Filters in division Digital Filters Design of Digital Signal Processing

Answer 1

Right choice is (a) True

For explanation: An effective remedy for curing the problem of overflow oscillations is to modify the adder characteristic, so that it performs saturation arithmetic. Thus when an overflow is sensed, the output of the adder will be the full scale value of ±1.
